JOSEPH nani am) HERBERT nsrnnny, OF orTUnwA, IOWA, AssIGNoRs To Dani IANUFACTUBING COMPANY OF IOWA, F OTTUM To all 'whom t may concern:

Be it known that we, JOSEPH DAIN and citizensof the United.y States, residing at Ottumwa, in the county of Wapello and State of Iowa, have yi11- .vented certain new and useful, `IniprOvesmooth bales;an d sorting means 1n ciprocating' plunger,

ments in Hay-Presses, of which the following is a specification, reference being had `to the accompanying drawings'. I Our` invention relates yto hay presses; 'more particularly a horse ppwer type shown in Patent #807911 lssued ecember 19, 1905; to Joseph Dain and has" for its object to provide certain improvementstherein; such improvements having to do'more particularly" with inserting the hay from the hopper-into the compression chanbely.- To this end our invention consist compression chamber inl advance of the rethereby lessening the manual work of operating the press. By saving for `the man feeding the press the time and labor of preparing the charges of hay and inserting them into the press, his attention and effort can be yconcentrated in preparing larger chargcsof hay in `position for our improved device to carry'mto the press,ithereby increasing to quite vvan extent the capacity of the machine or the days output of bales, For this reason it is not only a laborsaving which increases the revenue earning power of the press.-

.A further feature of the invention consists Iin so mountingthey hayinsertin means that it willentcr the compression 'c amber practically perpcndicularly to the path of the plunger face, best possible'manner for the makingof neat,

in operating theth'ay ina manner so that it will swing clear of the hopper and` not interfere with thel placing `charge in propcrpositionfor insertion.

The simplicity and positivelwmanner of operation is av further advantage' of our construction@y l We'accomplish the objects of ourl inven-k tion" as illu hereinafter described; What we `regard as newiszset forth inthe claims.

At its upper end the link 22 is attached to a rocking arm 23 mounted upon suitable brackets 24-24 as best shown in Fi 2. The rocking arm 23 has an extende portion 25 to which are attached hin ed brackets 26-26 upon which is pivotal y mounted a feeder arm 27, the lower portion of which is provided with hay engaging means 28-28, as best shown 1n Fig. 1.

29-29 indicate parallelin g links pivotally attached at their forward ends to a bracket 30 supported ends of the otally att-ac guide the feeder' arm and `hay engaging means 28-28 through the aperturev and into and out of the compression chamber 10 when the rocking arm 23 is actuated by the reciprocating vmovement of the plungerbar-11 through the medium of the connecting link .Y The pivotal point` of the pal'all'eling arms 29-29 in the bracket 30 is so related to the pivotal point of the rocking arm 23, and extension 25 in the by the bale-case 18. The rear brackets 24, that 'the hay engaging means 2S-28 travel approximately in a perpendicular line. When the feeder arm 27 has been moved to a point where the hay engaging means 28-28 are above the aperture or approximately in line with .ther'u'pper portion of the hopper 19e-19, then thelwerv portion of the arm 27 'or that part to which 'the hay engaging means 28-28 are attached,

swin 's Inore rapidly thanthe upper portion or w ere the parallelingarms 29-29 at- 'sof tach, which movement tends to carry the feeder arm andhay engaging means rapidly out of the ,way of the next succeeding charge of hay to be pitched into thehopper. The operation is` as follows: Vhen draft is' applied to the lever 8, one of the rollers GTG engages the link 5 and draws the pallbar 12 and plunger-bar 11 forward,lcai'rying the hay in front of ,the plunger 17 from the compression chamber 10 into the balecase 18. Simultaneous with the 'forward movement of the plunger 17, the link 22 rocks the arm 23 upward, moving the exten-A sion 25 also upward and carrying with 1t the feeder arm 27. At the extreme forward movement of 'the plunger 17, the parts 'assume the -position shown in' dotted lirios, at which' vtime ithe aperture`into the compres sioii'cha'mber-l() is closed and tl'ieghay'is' pitched into the hop "er 1S); 'ILAftethi roller-l 6-6 passes olf of t swinging 'link-bythe it is preferably attached paralleling links V295-29 are piv-l ed to the feeder ar'm 27 andswinging link 13, actuating it in such a manner as to reverse the movement of the swinging link 5, which forces the pull bar 12, and plunger-bar 11, and the plunger 17a backward. Simultaneously with this movement, the feed aperture is opened and the link 22 draws the rocking arm 23 downyward; the extension arm 25 carrying the feeder arm 27 with it, the same being guided properly through the feed aperture by the paralleling arms 29-29.

lVe thus-provide a very simple and ef- -ficient construction for auton'iatically inserting.r the hay from the hopper into the compression chamber and carrying it inio baleease 18 in such form as to he made into compact bales.

By our new and improved forni and arrangement of parts, we have. provided a machine which can be backed up to one side of a stack at abouty its middle point into close proximity with the stack so that one man can feed the hay into the comln'essionchamber without the necessity for the ha \,7 being handled a plurality oi times. 'l`his result is attained by reason of the arrangement of feeder mechanism so as to be reciprocated into and out of the feed opening from that edge of the feed opening located away from the stack, together with the arrangement by which the (.-omprcssion stroke ol' the plunger and the delivery of the completed bale are both in the direction away from the stack.

That which we claim as our invention and desire to secure by Letters latent is,

1. In a hay-press, the combination of a tween `the axis of said arm and said feeding opening, a link pivotally connected to sai bracket ata point a short distance above the pivotal axis .of4 said arm on said bale-ease and pivotally connected with the upper end vportion of the feeder-head, and means positively actuated by the movement of the plunger or operating said swinging arm to move the opening as the plunger reciproeates.l
